HeliCoil Thread Plug Gauges, Go No-Go Gauges

About HeliCoil STI Thread Plug Gauge

The accuracy of the finished thread when the HeliCoil insert is installed is dependent upon
the accuracy of the tapped hole. If the finished tapped hole gauges satisfactorily, the
installed HeliCoil insert will be within the thread tolerance. It is not necessary to gauge the
installed insert.
After the HeliCoil insert has been installed, the GO thread plug gauge may not enter freely.
However, the HeliCoil insert will always seat itself when the bolt or screw has been installed
and tightened.
